Having thus described our invention, what e claim is- 1. In a force-feed lubricator the combinaou with the reservoir having a at side Wall ith a suitable piston -chamber extending )wnward from its upper edge and an exittssage, a piston in said chamber, a slide iided by said wall, a spindle mounted in the all of the reservoir and projecting through 1 elongated opening in the slide, and means trried by the spindle for transmitting the otion of the prime mover to the slide, and a )nnection between the slide and piston-rod, lbstantially as described.'

2. A force-feed lubricatot' comprising a resvoir having a suitably-thickened wall, a vercal piston-chamber in said wall at one side )miiunicating` with said reservoir, a vertical alivery-chamber in said wall on the opposite de having a communication at its lower end ith the pistou-chamber, valves in said chamsrs, a slide working in a groove in said wall antrally of said chambers, a piston in the iston-chamber having a variable connection ith said slide, a spindle carried by said Wall nd projecting through an elongated opening in the slide, a cam journaled on the spindle, ribs on the slide embracing said cam, and pawland-ratchet mechanism for operating said cam from the prime mover, substantially as described.

3. In a force-feed lubricator the combination with the reservoir having a suitable piston chamber and exitpassage, of a slide guided in the wall of said reservoir, a spindle laving one end rigidly secured to said wall and projecting through an elongated openin in the slide, a cam rotatably mounted on said spindle and bearing against oppositelylocated ribs on the slide, a piston in the piston-chamber operatively connected with the slide, a ratchet-wheel rigidly connected with the cam, an arm rotatably mounted on the shaft and carrying a pawl engaging the teeth ot the ratchet-Wheel, and a second arm adjustably connected to said rst-named arm, substantially as described.
